To Ian Darwin <ian () darwinsys ! com>:
But the password has already been entered, that is previous the boot prompt. When I type "set tty com0", would that immediately switch console? I thought it established the console for the single user mode while loading /bsd (typical white letters on a blue background). About the "pins"; yes, those are the ones. But I was assuming to use them on both ends. Are you suggesting the use of an USB to Serial adapter to safely disconnect the USB end of the cable and that it would make it then safe to disconnect the other end too?
